This article lists characters that appear in Transformers: Cybertron, the third chapter of the "Unicron Trilogy" series of the Transformers franchise. The series features the entirety of planet Cybertron's civilization evacuating the planet to Earth when it is absorbed by a black hole left via the destruction of Unicron. The Autobots act as the main protagonists of the series, with the Decepticons as the main antagonists. Various characters originate from fictional planets shown throughout the series.

Originally, Cybertron was created in Japan as a separate standalone continuity called Transformers: Galaxy Force, but it was dubbed and edited into Cybertron. During the dub, most characters were renamed into new or previously established character to match with the continuity (e.g. Sideways, Hot Shot, etc.) Cybertron features a large cast of characters, something which has not been seen since the original 1980s cartoon. This show also features an incarnation of popular character Soundwave, again, not seen since the 1980s cartoon.

As the Great Commander of the Autobot military, Supreme Commander Optimus Prime (Soshireikan Galaxy Convoy) organizes the evacuation of Cybertron and the relocation of the planet's inhabitants to Earth when the Energon Sun went supernova. Although a stern and methodical leader, he is a compassionate robot who deeply cares for each of his subordinates. At first, Prime is firmly opposed to interacting with the natives of the worlds the Autobots visit, but soon comes to realize the benefits of the allies the Autobots gain.

Prime transforms into a fire engine, and can convert into a secondary flight mode, or merge with his trailer into Super Mode. Later using the Matrix of Leadership replacing the role of the Spark of Combination, he combines with his fellow Autobot Leobreaker to form Savage Claw Mode (Liger Convoy), and with Wing Saber to form Sonic Wing Mode (Kosoku Kido Soshireikan Sonic Convoy) though the Autobots claim when Prime and Leobraker combine for the first time, "I didn't know Autobots could do that".

Whether he or Galvatron are the stronger, or if both are in perfect balance is unknown, as although Prime did ultimately destroy Galvatron in one final blow, it was with Vector Prime's sword, given to him in the last few seconds before they clashed for the last time. His Cyber Key Power makes his cannons more powerful ("Galaxy Cannon: Full Burst!). As Optimus Breaker, his Force Chip special attack was Liger Grand Break; as Optimus Saber, it was Sonic Double Impact or Galaxy Caliber. When he uses Sparkdrinker in Super Mode, he uses Galaxy Giga Crush.

As Optimus Prime's second-in-command, Jetfire (Dreadrock) always follows orders, but he is willing to take matters into his own hands to get things done. Now having picked up the native accent of the planet Nebulos (similar to the Australian accent), Jetfire transforms into a cargo plane based on an An-225 Cossack and can unleash a pair of twin cannons through the use of his Cyber Key Power (Dread Cannon - Full Burst, Afterburner Blast Attack in English dub). He also has a turbine wind attack (Jetstream, Turbine Wave in the English dub). In one episode it is revealed that he has a fear of needles. He became leader of Cybertron after Optimus Prime leaves for the Space Bridge Project.

Back in the day, before he joined Rodimus Prime, the elderly Landmine (Guardshell) trained many young Autobots, including his old friend Mudflap and Optimus Prime himself. During the opening stages of the crisis that sprung up around the black hole, Landmine was transported to Earth by Vector Prime to save him from the black hole's power, where he met and befriended the three human children who became the Autobots' allies.

He transforms into a payloader, and can generate whirlwinds with the bladed wheels unleashed by his Cyber Key Power (Tornado Cutter, Cyber Tempest in the English dub). He also seems to be an homage to the Armada Character Scavenger, in transformation and role (as Optimus' mentor).

Mudflap (Demolishor) was an Autobot mentored by Landmine who was among those who evacuated from Cybertron and went into hiding on Earth. Growing dissatisfied with the Autobots' mission and human customs, he was persuaded by Starscream to join up with the Decepticons in a misguided attempt to try and save the galaxy without worrying about the affairs of humans.

However, he found he could not stomach the Decepticon way of doing things, and ultimately left them; consumed with guilt over what he had done, he was given a second chance and welcomed back into the Autobot fold by Landmine. He speaks with a French accent.

Mudflap transforms into a crane truck. His Cyber Key extends his crane arm and deploys a massive saw blade (Mega Crane Blade), and also activates an arm-mounted missile-launcher.

Wing Saber (Sonic Bomber named for the Zone Autobot) was first seen in Energon as a rebuilt Wing Dagger who could combine with Optimus Prime. Between the events of Energon and Cybertron, Wing Saber let his powers and the Autobots' victory get to his CPU. They had a little trouble rescuing a lost human astronaut from an asteroid belt near planet Chaar. From there, Wing Saber broke every rule in the Autobots' standards, he even attacked Optimus. After the Energon Sun turned into the Grand Black Hole, Wing Saber's memories were warped by the hole's spacetime distortion. He came back as soon as the Autobots and Decepticons tried to take the Omega Lock from Starscream, forcing him and Optimus to combine.

The brash youth of the Autobot team, Hot Shot (Exillion/Exigeyser) has a need for speed. An avid racer, he takes pride in the fact that he considers himself the fastest in the universe. Once on Velocitron, the Speed Planet, however, Hot Shot finds his title challenged by the planet leader Override, leading to many races, and a personal conflict between duty and ego. Later in the series, after being damaged by Megatron, he is upgraded into a new armored vehicle form as part of the Cybertron Defense Team. Hot Shot becomes the leader of Velocitron when Override is gone, even though he is still an armored APC. The black hole wiped him of his memories of what he was and did in Armada and Energon.

Hot Shot initially transformed into a swift sportscar that could be boosted to even greater speeds through his Cyber Key Power (Accel Wing). After being upgraded, he now transforms into a military APC armed with multiple missile launchers, and his Force Chip power becomes Double X Shot or Battle Dagger. The Cybertron Defense Team can combine their Cyber Key special attacks against a single foe (Triangle Attack), such as Galvatron.

The Autobots' main technical expert, Scattorshot (Backpack/Backgild) spends most of his time in the base analyzing monitors. Though he can handle his duties with precision, he is known for being quite nervous and unsure of himself. After being damaged by Megatron, he was upgraded by the Omega Lock and made a member of the Cybertron Defense Team, becoming more sure of himself. He speaks with a Southern accent (which possibly is a homage to Ironhide).

Prior to his reformatting, Scattorshot transformed into a half-track missile launcher vehicle with Cyber Key Power grenades ("Ground Shot Up"/"Land Shot", Missile Storm in the English dub). In his recreated form as a missile launcher tank, his Cyber Key Power transforms his launchers into a powerful rifle and rocket launcher ("Twin Search Missile" in Galaxy Force). The Cybertron Defense Team can combine their Cyber Key special attacks against a single foe (Triangle Attack), such as Galvatron.

Red Alert (First Aid/First Gunner) is the Autobot Medical Expert and Chief Science Officer, as well as a long-time veteran of the Cybertronian wars. After the events of Armada and Energon, he gained a British accent. When Red Alert and Hot Shot were sent to Velocitron, his matter-of-factness lead him to clash with the younger Autobot. Later, like Hot Shot and Scattorshot, he gained a new form after being damaged by Megatron and became part of the elite Cybertron Defense Team.

Red Alert initially transforms into an ambulance armed with an electron wrench, a repair hammer, and two Photon Beam cannons activated by his Cyber Key (Photon Beam). After reformatting, he became an armored missile launching vehicle, equipped with a massive missile that generates powerful energy blasts (Giga Vanisher). The Cybertron Defense Team can combine their Cyber Key special attacks against a single foe (Triangle Attack), such as Galvatron.

The Cybertronian starship called the Ogygia came to rest on a barren world, which its inhabitants soon dubbed Velocitron, the Speed Planet. The world was decorated with vast race tracks, and the starship's occupants spent their days competing in races until, by the present day, their descendants filled their time with nothing but. The entire culture of Velocitron is built around racing and speed, and its Cyber Planet Key is, naturally, a racing trophy that can only be acquired by defeating the planet's leader.

Long-time ruler of Velocitron, Speed of Sound Commander Override (Onsoku Shireikan Nitro Convoy)'s life is dominated by racing, to the extent that she would not impart information, or even hold a conversation with anyone if they did not face her in a race. When Hot Shot arrived on Velocitron, the noble goals of the young Autobot swayed her to their side, and she joined the heroes in the greatest race of all - the race to save the galaxy. Override transforms into a race car (most likely a Lotus), and her Cyber Key power allows her to boost her engine speed (Nitro Boost). She is armed with a double-barrelled blaster activated by her Cyber Key (Mach Shot).

Override was originally conceived as a male character, and appears as such as in Transformers: Galaxy Force, the Japanese counterpart of Cybertron. Cartoon Network's desire that the show have a greater female presence saw Hasbro recast Override as a female - a change that, though seeming sheer coincidence, functions very well, given the character's friendship with Lori and rivalry with Thunderblast.

During a regular race on Velocitron, Override was making everyone else eat her dust when suddenly, Megatron appeared right in front of her way. Megatron introduced himself to her and asked where he could find Override, the leader of the planet; as it turned out, he had found her. He asked where he could find the Cyber Planet Key, and Override challenged him to a race to get that info. He accepted, but Override took the victory in a photo finish. She told him she didn't really know about the key and just wanted to race; Megatron promised to tell her all about it at their next meeting. Later, at Override's favorite track on top of a mountain, Megatron again questioned her about the Key. He tried to get the location out of her by offering great reward, but Override was not interested - after all, she already had the Planet Cup, the most valuable object on Velocitron. Megatron copped that the Cup must be the Key he was seeking, and so challenged Override to another race. Just before they began, Hot Shot, who had been spying on the two, jumped in to compete on behalf of the Autobots. Megatron warned that Hot Shot was part of an evil organization, while Hot Shot maintained that it was the Decepticons who were the evil ones. Override wasn't interested in any of this, and told them to just race.

In the race, Megatron quickly fell into third place due to his car mode's inferior maneuverability. Hot Shot raced well and almost won, but was fired upon by Ransack and Crumplezone. Sure enough, Override won, but immediately assaulted the evil duo for assuming she couldn't have won on her own, and they quickly fled. Override complimented Hot Shot on how fast he was and said they could talk about the key next time they raced. She raced against Hot Shot again the next day, and gave him an impressive head start. This proved not to be enough for Hot Shot, however, as Override quickly closed the gap. Hot Shot managed to tap the power of Velocitron and activated his CyberKey, giving him a speed boost; however, he quickly crashed into a wall, taking him out of the race. Override cruised to an easy victory and drove off, looking forward to racing him again. She later encountered Ransack and Crumplezone bullying Dirt Boss. She tried to help him, only to be brushed off by the victim himself for some reason. Override went on her merry way, unaware that the Decepticons had just gained a new ally. Some time later, while doing laps of her private race track, she was approached by Optimus Prime, who also asked for the Cyber Planet Key. Prime tried explaining the situation, and even asked if he could just borrow it, but to no avail. Override told him that she'd heard the same story from both Megatron and Hot Shot; since she had no reason to believe any of them, the trophy would go to whoever won the race.

The next day saw the start of the Planet Cup, with Override as the favorite to win. She got off to a good start, closely followed by Dirt Boss. Hot Shot suffered from some early technical trouble, but soon managed to pull into third. She maintained a strong lead throughout the first heat, finishing first without major interference from the cheaters in the back. In the second heat, Override was pushed into second just before the narrow straightaway. She caught up to the leader, Hot Shot, on the stairs portion of the course by transforming into robot mode and running down them. Hot Shot quickly did the same, while Dirt Boss came up quickly behind both of them, his off-road tires allowing him to traverse the stairs easily. However, Ransack managed to literally leap into pole position by the clever use of springs, and rearranged the direction signs in the city portion to send the leaders on a wild goose chase. Override, Hot Shot, and Dirt Boss all fell for this ruse, but Hot Shot was alerted to the deception by Landmine. Hot Shot told Override about the situation, claiming he wanted to beat her honestly; Override was confused by this display, but still took his advice and returned to the correct track. Soon enough, she once again pulled into first place, but then Ransack and Crumplezone caused the tunnel she was driving through to collapse, trapping her. Hot Shot saved her despite losing first place, again saying it was simply a matter of Autobot honor. This only added to Override's confusion, and she would have lost the race altogether if Brakedown hadn't pointed out everyone else was passing her. In the end, she finished in a respectable third position. Before the third heat, she fitted herself with off-road tires, while Ransack and Crumplezone watched. When the race began in earnest, she avoided much of the initial drama, but eventually ended up being attacked by Dirt Boss, who was frustrated at the idea of someone else doing well in the off-road part of the race. She was saved by the accidental aid of Ransack and Crumplezone, who tried to shoot at her but hit Dirt Boss instead. The three villains fought among themselves, allowing Override to claim first place.

Override was then among the four remaining competitors, all of whom were chosen by the Cup to compete in the final. She and Hot Shot easily pulled ahead of Ransack and Crumplezone, who soon dropped out of the race. The troublesome twosome then tried to steal the trophy, but Override and Hot Shot stopped by to blast them away. They then continued their race, with Hot Shot taking victory in a photo finish. Override was initially shocked, but congratulated him on a well-earned victory and strong competitive spirit. Just as the force field around the Cup came down, Megatron and his cronies arrived to steal it. Optimus Prime, Vector Prime, and Leobreaker arrived from Jungle Planet to stop him, and Override took part in the battle. She and Hot Shot jointly tripped up Megatron, and Override herself grabbed the trophy. With the Decepticons driven away, Override personally presented the trophy to Hot Shot. Impressed by the Autobots' teamwork and collective honor and heroism, Override asked to join them in their quest, and was readily accepted. She accompanied them back to Earth, and as a native of Velocitron, was given the honor of inserting her planet's Key into the Omega Lock. As soon as she did, the Lock revealed the location of the Ancient Decepticons buried in the Arctic. Override accompanied the Autobots on their investigation, but they didn't find anything. When they got back, Coby repaired some of the damage she had suffered, and she promised to take Lori to Jungle Planet when fully healed. Lori would soon get her wish, as Optimus Prime returned from Jungle Planet and asked Override to accompany him to plead his case to Scourge. Override, true to her promise, brought along Lori to represent Earth, over the protestations of the other Auobots; Hot Shot was also present.

When the group arrived on Jungle Planet, they were soon attacked by a group of Decepticons led by Starscream. Override engaged Ransack and Crumplezone, but rather than fight, she challenged them to a race. The two villains quickly sped off to try and win, while Override let them go so she could concentrate on the battle. Starscream and Thundercracker were quickly dispatched, and so Override and the others proceeded to Scourge's temple. Override and Lori both pleaded with Scourge to do the right thing, but the dragonbot was only interested in dueling Optimus Prime and Leobreaker. Prime and Leobreaker won by the use of their Savage Claw Mode and claimed the second Cyber Planet Key for themselves. However, Megatron would not be denied, and attacked Jungle Planet with all his gathered forces. To counter his assault, Vector Prime came up with the idea of distributing several boxes to teams of Autobots, one of which contained the real Key, and the rest were dummies. Crucially, nobody would know which box was which. Override and Hot Shot paired off, and sped into the jungle with one of the boxes. They were pursued by, surprise surprise, Ransack and Crumplezone, who after considerable fighting and racing actually managed to grab the box. Fortunately, it turned out to be a dud (and a booby-trap as a boxing-glove on a spring)—Snarl and Leobreaker had the real one. With the battle won, the Autobots returned to their base on Earth along with new recruit Snarl, and Leobreaker inserted Jungle Planet's Key into the Omega Lock. Once again, the location of the Ancient Decepticons was revealed, this time to much greater precision. While four of them went off to investigate, Override stayed back at the base as backup. It turned out she would be needed, as Optimus Prime, Landmine, and Leobreaker found themselves trapped in a cave with Starscream and many thousands of Ancient Decepticons. Override, along with Hot Shot and Red Alert, raced out to save them, meeting up with Jetfire underground. They saved their comrades, and then returned to civilization to deal with Starscream. They arrived at the scene of the battle, where Vector Prime and Snarl were desperately attempting to hold off the Ancient Decepticons. Worse, they also came under attack by USAF jets, who did not realize the difference between Autobot and Decepticon. Just when things were looking their worst, Evac and Crosswise joined in the fray. They held off Starscream's forces for a while, but were forced to retreat when Optimus Prime was injured. However, some good came out of this—Evac revealed that the third Cyber Planet Key was located on Earth. Unfortunately, it was by then in the hands of Starscream.

The Autobots retreated, Optimus Prime particularly concerned about human civilian casualties. Override offered to let them set up base on Velocitron, and Optimus Prime gratefully accepted. They moved out on the Space Bridge, but just before they could pass through the dimension gate, they were attacked by Starscream. Override and the others made a valiant stand, but Starscream eventually proved victorious, claiming the Omega Lock and the two Keys the Autobots had acquired for himself. As if that wasn't bad enough, Megatron and his crew escaped from the prison in which they had been sealed by Starscream and began to rampage across Earth, together with Scourge. Override took part in the effort to drive them off, working with Crosswise to take down Ransack and Crumplezone. She and Evac then managed to distract Megatron long enough for the heavily injured Hot Shot, Red Alert, and Scattorshot to be evacuated to safety. The two planet leaders actually managed to beat up Megatron to such an extent that he tried to flee into the firedimension, only for Optimus Prime to douse the portal before he could pass through. His back to the proverbial wall, Megatron lashed out and floored the two of them, only to be stopped by the timely arrival of the three injured parties, now rebuilt as the Cybertron Defense Team". Leaving the lads to try out their new guns, Override, Evac, and Optimus Prime drove through one of Vector Prime's portals to Starscream's island base. Evac brought her to the island by a form of water skiing, during which she shot Thunderblast out of the water. On the island, Override dealt with Lugnutz, at one point actually riding him before passing him to Snarl. She also helped beat up Crumplezone, and took part in the first battle against the giant Starscream. Partway through that battle, word came from Cybertron that the Cybertron Defense Team was being overwhelmed by vast numbers of Scrapmetals, and so Override, Evac, and Leobreaker left the battle to go help them out, taking the Omega Lock with its three Cyber Planet Keys with them. Megatron and his forces pursued, and Starscream also sent Thunderblast after them. During their flight, they ended up stymied by a badly warped section of the space bridge which they couldn't cross, and the Decepticons quickly caught up. However, the three managed to tap the power of the Lock and, powered up with burning justice, streaked across space to Cybertron, much to Override's surprise and amazement. Upon arrival, the three found the Cybertron Defense Team desperately fighting a losing battle against the hordes of Scrapmetals. Just after they arrived, Megatron turned up with Scourge, Thundercracker, and Thunderblast, but before they could wipe out the Autobots, Optimus Prime's team came by to save the day. Optimus Prime defeated Megatron in the fire dimension, and there was much rejoicing. The Autobots then plugged the Lock into the space in the OmegaTemple, awakening Primus. As the planet itself began to transform, Override and Evac grabbed the kids and jumped off the planet.

When Primus finished his transformation, all the Autobots worked to restore his mind, Override working with Leobreaker. Speaking through Jolt, Primus revealed the location of the last Key on Gigantion. However, before they could mount an expedition, the ghost of Megatron restored himself by the power of Unicron and began attacking. Override and the Cybertron Defense Team followed the specter to see what it would get up to. Megatron restored and empowered the injured Crumplezone, who along with Ransack immediately began harassing Override, leading to a tense chase across Cybertron's streets. Crumplezone was finally taken out by Hot Shot, and after a fight between Megatron/Nemesis Breaker and Optimus Prime/Leobreaker, all the Transformers raced full tilt for the Omega Temple. They arrived at about the same time and began duking it out. The Autobots won, and Override took part in the operation to destroy any remaining Scrapmetals. Override then worked with Landmine as part of an operation to re-energise Primus with the Omega Lock and Optimus Prime's Matrix, but this plan failed when Starscream stopped by at exactly the wrong time and absorbed a chunk of this power, growing to planet size. Primus himself laid the smackdown on Starscream in a particularly awesome manner; after this, Override contacted Clocker and Brakedown on Velocitron and had them (and Dirt Boss, apparently) dig up with Ogygia so that the Autobots could travel to Gigantion.

The Autobots loaded up the Ogygia and set off on their way, but as they travelled through the wormhole, they were confronted with an asteroid too big to steer around. All of the Autobots combined their Cyber Key Powers to blast a massive hole right through it, allowing them to continue on. On Gigantion, the Autobots met up with Metroplex and Quickmix. After reassuring them that they weren't from Planet X, an alarm was raised that Menasor and the Decepticons were attacking the lower levels. The Autobots and their new friends sped down to investigate, and Override and Evac jointly took on Menasor, eventually beating him. As their search continued, Override was the fourth to be incapacitated by the Cyber Planet Key-powered Megatron, now calling himself Galvatron. She tried desperately to drive away from him, but this time, he was faster than her. However, she was able to warn Optimus Prime, who did manage to defeat Galvatron. When she had been repaired, she accompanied the Cybertron Defense Team and Coby (piloting the Cobybot) in infiltrating the Atlantis, which Starscream and Sideways had piloted to Gigantion in the meantime. They rescued the imprisoned Bud, Jolt, and Reverb, and then escaped as Quickmix filled with cement the crevasse in which the Atlantis was parked. After Bud, Jolt, and Reverb were reunited with the rest of the Autobots, the good guys split into four teams to find a way down to the innermost layers of the planet.

Override was assigned a team with Wing Saber and Lori. They took an elevator to a lower level, where they were confronted by Thunderblast and Scourge. Before any combat could begin, however, Lori began berating Scourge, causing the massive dragon robot to flinch away from the tiny, squishy human until Thunderblast insulted Lori. After that, the robots started shooting; Lori and Wing Saber chased after Thunderblast while Override stayed to fight Scourge, the leaders of Velocitron and Jungle Planet finally coming to blows. This battle resulted in the ceiling getting a massive hole blown in it, and so the two combatants moved to a higher level. Scourge threw his axe at Override and missed, but almost hit Lori, who chose that precise moment to return from forcing Wing Saber to blow up Thunderblast. Terrified of Lori's wrath, Scourge fled, leaving Override and Lori to punch the wall in frustration. However, Lori's punch opened up a secret panel to an information center, where the two of them and Wing Saber were able to learn the story of Gigantion's war with Planet X, as well as the origin of Sideways and Soundwave. With this new information, they quickly rejoined Optimus Prime's team to tell them the story. They all proceeded down to the lowest layer, where they found Bud giving a lesson in leadership to Scourge and the Mini-Cons. Scourge let Metroplex and Vector Prime beat him up, after which Override stepped forward to have her turn, but Optimus Prime went ahead of her and thrashed Scourge so badly that there was no point in fighting him any more. Continuing their journey, they came across the area where the Lemuria was said to have lain. Override and Wing Saber sped on ahead to investigate, and found it partially buried in a large lake. Shortly after Optimus Prime's team showed up, Galvatron blew through the ceiling, bringing the remaining Decepticons with him. Wing Saber went back to help Optimus Prime, while Override waited for reinforcements.

Reinforcements soon arrived in the form of Landmine's team. Override and Evac went to join Optimus Prime and aid him in battle, and got smashed by Galvatron. However, they soon recovered and chased Galvatron into the Lemuria, arriving just as Landmine claimed the final Cyber Planet Key and grew to gargantuan size. Landmine proceeded to lay a massive smackdown on both Starscream and Galvatron, with some small help by Override and Evac. When Galvatron came back and stole the Omega Lock and the four Keys, Override stood back and watched as he fought Starscream, not wanting to get blown up. However, Galvatron still made off with the Lock. The Autobots tried to re-open the portal to their own universe, but they were attacked by a flock of Laserbeak drones, which only dissipated when the machine opening the portal was destroyed. In the end, it required the sacrifice of Vector Prime to return them to their own universe. Upon their return, Override returned to Velocitron to rally her forces against Galvatron's machinations. Just as Galvatron and his remaining Decepticons were preparing for their final assault on Cybertron, Override arrived with every Transformers on Velocitron (they raced there, naturally), at exactly the same time as the forces of Jungle Planet, Earth, and Gigantion arrived. Primus then merged the Ogygia, Atlantis, Lemuria, and Hyperborea into the Ark, to rid the universe of evil once and for all. However, Galvatron still possessed the Omega Lock, and used it to enlarge all of his loyal followers as well as himself to enormous size. Override led the forces of Velocitron against Crumplezone, exploiting the fact that the big lug's greater size had negatively impacted his maneuverability to cause him to crash into some asteroids.

Meanwhile, Galvatron fled into the deepest core of the UnicronSingularity. Optimus Prime combined with Wing Saber to pursue, but before he got too far, Override, Scourge, Evac, and Metroplex announced their intention to come with him, each to represent their own planet in the final battle. The humans and Mini-Cons also came. The five planet leaders all attacked Galvatron in a massive joint attack, after which the Decepticon commander tossed the Lock into the very center of the Singularity to prevent anyone getting their hands on it. The Keys separated from the Lock, and the planet leaders dived for them. Override grabbed the Velocitron Key, driving around an asteroid to get it. The other leaders were also successful, and they successfully combine the Keys with the Lock. This final act complete, they flew out of the Singularity and used the Lock and Keys to fully restore Primus, who blasted the Singularity closed. However, there were still a few loose ends to tie up. Jungle Planet had been shaken out of its normal location, and Override took part in the effort to restore it. She, along with most of the other characters, also stopped by on Earth's Moon to see Optimus Prime vanquish Galvatron for real this time. With evil defeated and the remaining Decepticons attempting to live peacefully, Override attended the first intergalactic peace conference to represent Velocitron. At this meeting, it was decided to follow in the footsteps of the Ancients and establish a galaxy-wide network of colony worlds, linked by space bridges. Override wished to take part in this mission, but could not leave Velocitron without a leader. To that end, she called a Speedia 500, which was won by Hot Shot. She formally handed over leadership of the planet to the young bot, and some time later returned to Cybertron. She said a tearful farewell to the kids before boarding the Ogygia with a large crew of Transformers and departing for parts unknown.

Override is a Female Autobot Warrior rumored to transform into a fluorescent red McLaren 570S with black/carbon fiber accents and a matching red interior. If reports and rumors are true, she will appear in Transformers: The Last Knight with this alternate form, due to the car being referred to as "The Lady" on set. It is also rumored that this same vehicle could be the Decepticon Widowmaker, whose role was replaced with Stinger, the Pagani Huayra KSI drone in Transformers: Age of Extinction. Whether it is one of the two, an all-new character, a returning character or neither is currently unknown. She also appeared as a Decepticon in the 2010 Transformers toyline as a redeco of Sideways.

Override led the crew of the Star Arrow, which was carrying an experimental Force Chip. The Star Arrow was attacked above Sandokan and crashed on the surface. The crew encountered Synthos, a scrap-monster powered by the Dark Heart. Override and the other Autobots fled from the monster and hid until Astrotrain attacked. When Astrotrain captured the Force Chip and headed towards Synthos, Override followed. She sought to prevent Synthos' Dark Heart from falling into Decpticon hands, but also desired to save the sentient scrap monster. The Autobots captured the Decepticon shuttle that carried Cannonball into battle and used it to capture him, Astrotrain, and the other Decepticons. After depositing them on the other side of the continent, the Autobots fled to Cybertron with the recaptured Force Chip.

Part of the Speed Planet theme, Override transforms into a sleek futuristic race car. Plugging a Cyber Planet Key into the rear portion of her car mode causes two non-firing blasters to flip out into attack position; this assembly becomes a hand-weapon for robot mode, and can also store on her back. Override's transformation is partially spring-loaded; pressing her black "front bumper" automatically flips her torso and arms into position, requiring only her lower body and backpack to be manually configured. She came with a gold-bordered Velocitron-style Cyber Planet Key. There are a few small deco changes between the Hasbro and Takara versions of the toy; Takara's has a gold face, black paint on the chest intakes and blue stripes on the thighs while Hasbro's has an orange face, an Autobot faction sigil on the left side of her chest, a less prominent stripe pattern on the inside shins and gives her Key the Key code "dy7p". This version of Override also was available in two different store-exclusive multi-packs. The first was a Wal-Mart set, including the Cybertron-series Tiny Tin version of the Race Mini-Con Team member Mirage. The second was a Target-exclusive "Drag Race" set with Hot Shot. This mold was used to make the evil clone Dark Nitro Convoy.

Override GTS (Deluxe class, 2006)

Override's first toy was redecoed into a non-show coloration, replacing her white for a light gray, and gaining more black in her scheme. She still came with a gold -bordered Velocitron Cyber Planet Key, though this one has the Key code "dj9n". Early solicitations for this toy used the name "Double Clutch", suggesting that at one time, it might have been under consideration as being a new character. However, the first true Hasbro announcement of the toy at BotCon 2005 was that it was Override again. This toy was repurposed into Shattered GlassElita One.

A young and spunky denizen of Velocitron, Clocker (Skids) is a student of the racing master Brakedown, who met and befriended Hot Shot when the Autobot came to Speed Planet. He transforms into a convertible race car, and his Cyber Key activated a double-barrelled blaster (Smash Burner). He was in the race for the cyber key, but was dropped after the second race.

One of the oldest residents of Speed Planet and a friend and teacher to Clocker, Brakedown (Autolander)'s wisdom as an experienced racer gives him a different perspective on situation than others, making him invaluable to young racers in training. Allying with the Autobots after meeting Hot Shot, he transforms into a dragster, and his Cyber Key activates a bladed weapon (Motor Blade). His relationship with Hot Shot is comparable to Hot Rod and Kup from the original G1 cartoon. He was in the cyber key race, but was dropped after the desert race.

Dirt Boss (Inch-Up) is the most specialized Transformer on Speed Planet when it comes to traveling on multiple terrains, from bumpy, uneven paths to muddy quagmires. He hates Override and seeks to defeat her in a race, which proved to be all the reason he needed to join up with Megatron's Decepticons. Defeated in the race for Velocitron's Cyber Planet Key, he broke off his ties with Megatron. He transforms into a monster truck, but can convert to a "high speed mode" with a widened wheelbase through the power of his Cyber Key. In robot mode, his key deploys twin shoulder blasters (Shoulder Vulcan).

When the Autobot starship the Hyperborea landed on the lush, green world of Jungle Planet, the ship's occupants adopted animal alternate modes, but as time wore on, they and their descendants took on the characteristics of the beasts they mimicked, becoming segregated and bestial. With parties of violent raiders attacking the weaker inhabitants, a feudal law of "Might makes right" came into effect, making the already untamed wilds of the planet even more dangerous.

As a former student of the master Backstop, Dark Commander Scourge (Ankoku Shireikan Flame Convoy) sought to bring peace to the Jungle Planet, but in using his vast strength to crush all opposition and accomplish his goal, he lost sight of his teacher's ideals and ruled the world through intimidation and shows of power. Hardened and cruel, Scourge espouses the mantra of "Might makes right," but he found his ideals challenged by Leobreaker and the Autobots.

When he was ultimately defeated in combat by Optimus Prime, his pride and jealousy motivated him to join the Decepticons (taking over Starscream's position as Megatron's second-in-command), but from the hard lessons from Lori, Bud, and the Autobots he would learn would eventually turn him to the side of light.

Scourge transforms into a dragon. His tail becomes a massive axe, while his Cyber Key deploys heads over his shoulers in both modes, unleashing a deadly stream of fire breath.

Overhaul (Jackshot) was once a famous Autobot soldier with a reputation for winning seemingly impossible battles. However, he was considered a loose cannon, and thus, felt alone. As a member of Optimus Prime's team, however, he realized he wasn't completely without friends or allies. Stranded on the Jungle Planet, he engaged planet leader Scourge in battle and called out to the power of the world's Cyber Planet Key when badly damaged, which reformatted him into the bestial Leobreaker (Ligerjack). His doubts cause Nemesis Breaker to be born and Megatron gains Dark Claw Mode ability. Ever since he became Leobreaker he tried to take down Scourge.

As Overhaul, he transformed into a military offroad SUV, and his Cyber Key Power allowed him to launch a piledriving missile from his chest ("Anchor Shot", Slam Attack in the English dub). Reformatted into Leobreaker, he gained a liger alternate mode and deadly Cyber Key Power claws (Platinum Claw, as well as Ultra Liger Drop), and could now combine with Optimus Prime into Savage Claw Mode (Liger Convoy, with the Force Chip special attack Liger Grand Break).

A zen master of combat, Backstop (Saidos) trained the weaker fighters of Jungle Planet, but at the same time, advocated the values of fighting only when necessary, and striving for peace, rather than fighting for fighting's sake. These were values that his student Scourge could not accept, and he left Backstop's tutelage; when the Autobot Overhaul arrived on the planet, Backstop and his last remaining student Snarl trained him, and sided with Optimus Prime's forces in the battle to save the galaxy. He transforms into a rhinoceros, and his Cyber Key extends his horn into a bladed battering-ram (Bloody Horn).

As Backstop's student, Snarl (Fang Wolf) was formerly friends with the planet leader, Scourge. He stayed at Scourge's side to keep an eye on his old friend, until Overhaul arrived on the planet and Snarl was branded a traitor for helping him. He formed a connection with the Autobot, and eventually left his planet to help Optimus Prime save the universe. He transforms into a wolf, with two armor-piercing fangs activated by his Cyber Key (Power Fang).

One of Scourge's troops, Undermine (Dinoshout) is somewhat shifty and underhanded. He transforms into a robotic Spinosaurus with a flail weapon for a tail, and a Cyber Key Power that deploys a blade from his fin (Crest Sword, Horn Blade in the English dub). He speaks in an English accent.

One of Scourge's troops, Brimstone (Tera Shaver) isn't very bright, and relies on Undermine and his leader to do the thinking for him. He transforms into a robotic Pteranodon, and his Cyber Key deploys twin blades from his wings (Slash Knife).

Eons ago, as part of a program to create a space bridge network linking planets across the universe, four Transformer starships departed for the four corners of the galaxy, each carrying with them a Cyber Planet Key. The starship known as the Atlantis came to Earth, hovering in the skies above the world before a malfunction caused it to crash into the ocean, giving rise to the human legend of the sunken continent of that name. The descendants of the Transformers aboard the Atlantis mostly entered stasis before the present day, though a few continued to operate in secret.

Guardian of Earth's Cyber Planet Key, Aerial Commander Evac (Koku Shireikan Live Convoy) has existed secretly on the planet for many years, repeatedly switching alternate modes and aiding humans in danger. One such human was a young boy named Franklin, leading the child to pursue knowledge of Transformers for years afterwards. Evac transforms into a rescue helicopter, and his Cyber Key activates a set of thrusters (Jet Booster) that can also launch missiles (Falling Missile/Homing Missile/Jet Missile, depending on his mood).

When Decepticons descended from those on the Atlantis began threatening burgeoning humanity, Crosswise (Autovolt) took on the role of "Monster Hunter" and dedicated himself to capturing and imprisoning them. He succeeded in sealing the Decepticons in stasis beneath the ice fields of Alaska, but he too was trapped, frozen in ice, until Earth's military uncovered him in the present day. Crosswise transforms into a car resembling a Bugatti Veyron, and his Cyber Key activates a set of twin missile launchers (Force Missile).

Originally, Crosswise was intended to be called "Smokescreen", leading to a production mistake that saw him referred to by this name during the original airings of his debut episodes on Kids' WB. However, by the time these episodes premiered on Cartoon Network, the dialogue had been re-edited to give him the correct name. The mistake was then drafted into a toy.

Although he was one of the Decepticons freed by Starscream, Lugnutz (Roadstorm) had very little interest in actually fighting for him. He's a very easy-going 'bot with a relaxed, hippie-like attitude that means he would rather be cruising Earth's highways than fighting Autobots. If any of them were to get in his way, though, he wouldn't be averse to blowing them away with his rifle, Dutch. He transforms into a motorcycle, armed with a grenade launcher activated by his Cyber Key (Side Machine Gun).

The fourth and final Autobot ship, the Lemuria, landed safely on this world. Some time into the colonisation of the planet, it fell victim to a tear in reality, and slipped through a wormhole into another dimension, where it was attacked by the warmongering inhabitants of the vile Planet X. Through the power of their Cyber Planet Key, the planet's inhabitants became gigantic in size and fought back, leaving Planet X with no option but to use their mightiest weapon, only to wind up destroying themselves in the process. Saddened by their planetary level of destruction, the Gigantions dedicated themselves to construction, covering their planet with gargantuan cities which they completed and then abandoned, moving on to the next project. To continue this ongoing task, they built new layers on top of the cities, repeating the process over and over, until the planet itself was colossal. In addition to the giant Transformers, Gigantion is also populated by Mini-Cons, who perform the small, intricate, detailed tasks of construction that the larger robots cannot.

For whatever reason, all the inhabitants of Gigantion speak with Scottish, German and Irish accents.

The leader of the Transformers on Giant Planet, Open-Mind Commander Metroplex (Kyoshin Shireikan Megalo Convoy) is the largest of the large, the bravest of the brave and the kindest of the kind. In the English dub, he speaks with a Scottish accent. He is physically powerful enough to best Megatron in mere seconds (an unequaled feat amongst the Transformers of this era), and joined up with the Autobots almost as quickly. He transforms into a bucket wheel excavator, and wields a gigantic axe, called Sparkdrinker. He can also assume a smaller "work mode" for more precise tasks.

He is partnered with the Mini-Con Drill Bit (Horribull), who becomes a drilling vehicle. He can mount on Metroplex's right arm or the back of his axe. He functions as a coordinator, and plans all of the Mini-Con work in Gigantion. Many of those Mini-Cons consider him the leader of their planet.

Metroplex lends Optimus Prime Sparkdrinker for Optimus to use as a bludgeoning weapon (Galaxy Giga Crush). His Cyber Key powers up Sparkdrinker (Megalo Crush/Axe Crusher), or he can throw it like a boomerang (albeit a very big one) (Megalo Boomerang).

Quickmix (Blender) is Metroplex's right-hand man and knows "a lot about a lot". His skill is as an advisor and a technical worker, but he can fight just as well as anyone, with a Cyber Key Power that transforms the drum of his concrete mixer alternate mode into a blaster (Mixing Cannon).

His Mini-Con partner is named Stripmine (Killbull), who transforms into a mining vehicle. He helps to operate Quickmix while the latter is in vehicle mode. Stripmine's function is Heavy Machine Operations.

A young Transformer from Gigantion who wanted to change his world's seemingly "out-dated" philosophy by force, Menasor (Moledive) fell prey to Megatron's influence, and joined the Decepticons. Ultimately, his Mini-Con partner Heavy Load (Bull Bull) showed him the error of his ways by leaping in front of Menasor's own drill. Unable to harm his own partner, he saw that he would only hurt Gigantion, and joined Metroplex and the Autobots. He transforms into a large-scale drilling machine, while Heavy Load becomes a dump truck. His Cyber Key power increase the power of his drills. His Force Chip special attack is Giant Drill.

As one of the first thirteen Transformers created by the race's deity, Primus. Vector Prime hails from the very beginning of Cybertron. Having removed himself from the linear universe eons ago, he existed outside of time, watching over the multiverse until the threat of the black hole emerged, forcing him to return to Cybertron and alert Optimus Prime's Autobots to the power of the Cyber Planet Keys. But at last, Vector Prime sacrifices himself to save Cybertron and to open the warp gate.

Vector Prime transforms into an ancient Cybertronian spaceship. His sword, Rhisling, is sharp enough to rend the fabric of space and time and open portals to anywhere in the galaxy, while his Cyber Key Power generates a protective forcefield but rarely uses it (Repulsion Field, Tachyon Shield in the English dub, other powers are Time Relief and Action Field). He is partnered with the Mini-ConSafeguard (Roots), and is the guardian of the Mini-Con Recon Team, who he encountered on his journey. Also stranded along with the Recon Team, Safeguard bonded with Vector Prime when he rescued them and became his personal partner. Often functioning as a scout, he transforms into a small jet-like vehicle that can mount to Vector Prime's arm as a blaster.

This trio of Mini-Cons hail from Gigantion, but were stranded in space and time when a game of hide and seek went away. Discovered by Vector Prime, they were brought to Earth by him, where they quickly befriended the Autobots' human allies Bud, Coby and Lori, due to having minds that function like human children's.

Jolt (Hop): Transforms into a helicopter and is obsessed with Earth culture, from television to movies to the internet. Jolt is the only Mini-Con who can speak English.

Six-Speed (Bullet, but due to Japanese pronunciation was misspelt on the subtitles as Blit): Transforms from a 2003 Bentley Speed.

The Cobybot (Coby Ramble in Galaxy Force) is a Scrapmetal that Coby Hansen refitted as his own pilotable Transformer in the Cybertron series. Like most of the Scrapmetals, the Cobybot transforms into a "spider-tank" vehicle. Its special attack is Hissatu Coby Shot.

A Coby Ramble toy was released as part of the EX-02 Sonic Convoy, which is a giftset that was released exclusively for Toys "R" UsJapan.[1] A reviewer at TFORMER (a division of Entertainment News International) noted that the Coby Ramble toy was simply a "remold and repaint".[1]

Another Galaxy Force Coby Ramble toy, a remold of the Scrapmetal toy, was made exclusively for Takara.[citation needed]

Trapped within an energon sun at the conclusion of Transformers: Energon, Master Megatron was freed from his imprisonment when the sun collapsed into the massive black hole that threatened Cybertron. Having absorbed the remnants of Unicron's armor and power into his own body, Megatron is now arguably the most powerful Decepticon, and seeks to use the power of the Cyber Planet Keys and the black hole to remold the universe in his own image. Despite recruiting natives from all the different worlds that the Transformers visited, Megatron was continuously met with failure, but upon his defeat by Metroplex on Gigantion, his Armor of Unicron tapped into the world's Cyber Planet Key and upgraded him into the insanely powerful Master Galvatron. He won more battles as Galvatron and stole the completed Omega Lock for many episodes.
Megatron is a Triple Changer, transforming from a Batmobile-like dragster into a Cybertronian jet. He can project devastating electrical blasts from his hands, and his Cyber Key activates many powers, including vehicle-mode thrusters, a claw shield (Death Claw) and his deadly "Death Machine Gun", (Death Machine Gun) with which he fatally injured Hot Shot, Red Alert and Scattershot. He could also combine with Nemesis Breaker to form Dark Claw Mode (Liger Megatron) for a short period of time, with a similar Cyber Key power to Optimus Prime's Savage Claw Mode Cyber Key attack (Liger Death Strike).
As Galvatron, he retained all his previous attacks, could project dark energy, and shape it into a sword. In his final battle with Optimus Prime, he gained a new transformation in which his back wings/cape formed a cannon on his chest, which fired dark electrical energy (Death Cannon). His armor can also restore him.

The only Decepticon to take on an Earth mode, Thundercracker was first mentioned in Armada when Starscream was contemplating his supercharged color scheme. When Cybertron came to air, Thundercracker was an enthusiastic fighter somewhat lacking in intelligence and combat skills who spoke in a Southern drawl accent. He has a tendency to come up with grand but largely ineffective special attacks (The Japanese version has him parodying lines said in Mecha anime characters), and would rather be a winner than be evil. He transforms into a Su-27 Flanker, and his Cyber Key activates the blaster in place of his left arm and in jet mode the Cyber Key power gives him a gun on his back (Thunder Hell, English: Thunder Cannon /Super Hell Special Deluxe/Big Spinning Thunder Hell Scattering Fireworks, English: Rain of Ultimate Destruction/Sure Kill Ultra Hurricane Slash And Crush Shoot, English: Triple Spinnin' Laser Willmaker/Drill Spinning Thunder Hell Electric Drop/Hissatu! Super Electric Lightning Shock Electric Thunder Cracker Punch!, English: Super Electric Lighting Thundercrackin' Punch/Hyper Ultra Big Missile Full Burst Maximum Alpha!/Hyper Ultra Big Missile Full Burst Maximum Beta Two). The Decepticons often ride on him a lot.

Also freed from the sun upon its collapse, Starscream assumed the position of Megatron's second-in-command. But his experiences throughout the Transformers: Armada and Energon conflict had shaped Starscream into a bitter mech with his own ambitions, and he sought to acquire the power of the Cyber Planet Keys himself. Scheming with the mysterious Sideways, Starscream liberated the ancient Decepticons trapped on Earth and acquired the Omega Lock and three Cyber Planet Keys, allowing him to tap the power of Primus and grow to a gigantic height. Operating as a third factor in the remainder of the conflict, Starscream battled with Megatron, Optimus Prime and even Primus himself by growing skyscraper size and planet size.

This big green brawler is the muscular half of the "Gruesome Twosome" and is hardly ever seen without his partner, Ransack. Crumblezone (Landbullet) is not especially bright, but his bulky frame possesses incredible speed when in his three-wheeled dragster mode, and great strength in robot mode. During a later battle on Cybertron, he was badly injured by a horde of Scrapmetal, but Megatron used the power of his Unicron Armor to reformat him into "Dark Crumplezone" (Armbullet). His Cyber Key Power activates a pair of massive missile launchers (Land Bazooka, Arm Bazooka after his upgrade). In the final Planet Cup race, he modified himself to give himself extra speed (Ultra Tune Level 2 Ignition), but still lost.

The smaller and more "intelligent" member of the "Gruesome Twosome" (although that's not saying much), Ransack (Gasket) makes up for his small size in nimbleness, agility, fairly quick wits, and the fact that he has a bigger partner that can beat up people for him. He transforms into a motorcycle with Cyber-Key-activated boosters that act as a double-barrelled cannon in robot mode (Exhaust Shot/Exhaust Boost). In the final Planet Cup race, he modified himself to give himself extra speed (Reverse Tune Ignition), but still lost.

An evil doppelganger of Leobreaker who was born from Leobreaker's doubts and the dark power contained in Megatron's Unicron Armor. Nemesis Breaker (Dark Ligerjack) can combine with Megatron into Dark Claw Mode (Liger Megatron, with the Liger Death Strike Force Chip attack), in opposition to Optimus's Savage Claw Mode. His Cyber Key power is the same as Leobreaker. He is more beast than Transformer, and only speaks through growls and roars. Ultimately, he was destroyed by Metroplex, returning him to the darkness from whence he came.

Thunderblast (Chromia) is an ancient female Transformer who was locked up by Crosswise and initially served Starscream, but turned to Megatron's side based on how hunky he was. She has a flighty, fun-loving, girlish personality, but ultimately, her only loyalty is to herself, and she will join whomever is most powerful. She transforms into a speedboat, and her Cyber Key transforms her missile launcher weapon into an even larger rocket launcher (Phantom Wave). She is also lava impervious as she once swam on it, and she is a master of water travel.

Planet X was home to weapon manufacturers/dealers, thieves, murderers and villains of all walks of life, who took their planet on a voyage of galactic conquest and destruction. That voyage came to an end, however, when Planet X encountered Gigantion, and destroyed itself in the ensuing war. The scattered survivors of Planet X allied themselves with Unicron in hopes of attaining revenge on the Giant Planet in the future, and served his will by acting as enigmatic operatives of misdirection and distrust amongst the Transformers. They pulled a gun at something. Planet X was destroyed!

This master of deception had previously served Unicron by acting as an avatar for his spark during the war for the Mini-Cons in Transformers: Armada, and was preserved by his dark power following his seeming death at the end of that conflict. Returning during the search for the Cyber Planet Keys, Sideways (Noisemaze) aligned himself with Starscream, considering him the best chance he had at revenge against Gigantion.

Sideways transforms into a spacecraft. His Cyber Key activates an arm-mounted bladed weapon, and switches his faction signal back and forth from Autobot to Decepticon.

Soundwave makes his entrance later in the search for the Cyber Planet Keys, offering to guide Megatron and the Decepticons to the wormhole that would lead them to Gigantion. Once on the planet, he joins with Sideways, and they both attempt to acquire the Omega Lock and Keys for themselves, only to be blasted into another dimension. Unlike his other counterparts, this one sounds like a deadpan 80s' rave club DJ.

Soundwave transforms into a stealth jet fighter, and is partnered with the Mini-Con-like robot, Laserbeak (Killer Condor). Laserbeak transforms from a condor into a battery bomb that stores in Soundwave's chest compartment, which deploys through use of his Cyber Key (Blaster Gun). (The animated version of Soundwave is not shown using his Cyber Key to "eject" Laserbeak, or to use it at all.)

An army of drone-like, mutant mechanical lifeforms. While they bear the Decepticon symbol, they serve neither Megatron or Starscream, and act like swarms of vicious insects. They come from worlds neighboring Cybertron, and swarmed to the planet when it was abandoned during the black hole crisis. They were faced down by the Cybertron Defense Team, who wiped out a large number of them. However, the Scrapmetal population clearly survived, as shown by the swarm that attacked and nearly killed Crumplezone. Later, a destroyed Scrapmetal was used by Coby to create his own pilotable Transformer, the Cobybot. They all transform into "spider-tank" vehicles, and come in varieties of red, blue, and yellow. They too have a cyber key and powers which make their cannons unsheathe a sword, but this was never seen in action.

The benevolent creator of the Transformers, Primus is the true form of the planet Cybertron. Each of the Cyber Planet Keys contains a portion of his power; upon the collection of all but the Gigantion key, Cybertron transformed into Primus's robot mode and defeated Starscream in battle using his own moons as weapons. Subsequently, the acquisition of the Giant Planet key reunited Primus's spark with his body, and he used his power to seal the black hole and recreate Cybertron as a new, idyllic world. His Cyber Key power unleashes energy from his hands which he used on Starscream but he deflects it.

As Primus's brother and ancient foe, Unicron sought to destroy life where Primus sought to protect it. Having been battled by the Transformers in previously in Armada and Energon, Unicron was ultimately defeated when his spark was imprisoned by Primus within an energon sun. The destruction of Unicron - the embodiment of evil - in this manner, however, caused a fundamental imbalance in the universe, which caused the sun to collapse in upon itself, creating the massive black hole that threatened not just Cybertron, but the entire multiverse. Although Unicron does not bear a Decepticon insignia on his body, he is assumed to be on the Decepticon side due to his extreme level of evil and his rivalry with Primus.

Coby Hansen (voiced by Samuel Vincent in English and by Yukiko Tamaki in Japanese) is the primary human character in Cybertron. The character has been used in the television series, comic book series, and collection of children's toys manufactured by Takara Tomy in conjunction with Hasbro. In the series, he is a mechanically-inclined 14-year-old who is often called on by the Transformers to do repairs.[2] He lives in Colorado with his younger brother, Bud,[2] and older brother, Tim and enjoys dirtbike racing and has worked at a mechanic's shop. Coby and Bud, along with their friend, Lori (the only female of the series),[2] befriended the Autobots after finding and aiding the damaged Landmine.[3] He develops a friendship with Landmine, and aids Hot Shot on Velocitron.

Later in the show, he actually refits a destroyed Scrapmetal as his own personal vehicle called the Cobybot ("Cobyrumble" in Galaxy Force), earning himself an Autobot Commission and an active role in the battles after he used it to save Bud, who was trapped among the Decepticons.[4] He is very protective of his little brother Bud.

From the onset of the series, Coby has a somewhat antagonistic relationship with Lori; their first conversation is an argument (in the Japanese version, she mocked him for liking machines to living creatures). However, as the series progressed, the two of them developed a strong unspoken bond, strengthened by their time with the Autobots.[5]

In the finale, as the Autobots prepare to leave, in order to begin construction of a new space bridge, Coby is joined by Lori as he sits on his drone. He tells her that he intends to study hard and someday go up into space to help out; Lori replies to the effect that she'll see him there. The pair hold hands and (in a first for a Transformers series) share a kiss.

The epilogue montage shows both Coby and Lori in space suits, successfully keeping their promise to meet up in space. The final scene of Galaxy Force is a picture of their wedding, surrounded by their family members, as well as Landmine, Six Speed, and Optimus Prime in the background together.

Coby's younger brother, Bud is a kid through and through. He likes things that kids like, and he daydreams like kids do, although in Bud's case, his daydreams often become reality thanks to his friendship with the Autobots. Very little can phase Bud - his unrelentingly positive attitude keeps him from worrying too much about anything, even the possibility of his own demise. As the ending credits of the final episode show, he won an Academy Award for the documentary he produced about his adventures.

Lori (voiced by Sarah Edmondson in the US dub) is the most level-headed of the group, she keeps Coby and Bud under some degree of control. As a city girl, she was not best pleased when her parents moved from a city to a small town in Colorado, but the adventures she had with the Transformers soon took her mind off that. Along the way, she gains a friendship with Override, and forms a connection with Scourge - both refer to her as "little sister". She even developed a rivalry with the female Decepticon Thunderblast. The ending credits show that she and Coby eventually get married.

When the young Franklin was saved from a raging river as a child by Evac, he dedicated himself to acquiring information on the Transformers, eventually becoming a government agent and, to the surprise of the Autobots' child friends, an ally of the Autobots themselves. At the end of the series, he developed a romance with Dr. Suzuki, who - to his surprise - revealed they were engaged. The ending credits show that they do get married and have a child.

Professor Suzuki (voiced by Tabitha St. Germain) is not exactly held in high standing amongst her scientific colleagues due to her ideas about alien beings and the Hollow Earth theory, but that doesn't bother her. She quickly and easily befriends Coby, Bud and Lori due to their own open-mindedness about her theories, and becomes involved in investigating the Transformers for the government. When Colonel Franklin revealed that his motives were peaceful, she became friendly with him, and eventually decided that they were going to get engaged. The ending credits show that they married and have a child.

Tim Hansen: Coby and Bud's older brother. Has an unnamed girlfriend or fiancé.

Stanton: A mechanic who Coby spends a lot of time working with.

Coby and Bud's father is a brown-haired man; he and Coby have been seen racing dirtbikes together. His mother is blonde.

Lori's father, Ernie, is a real-estate developer who enjoys amateur astronomy. Her mother is a somewhat portly woman, and her career is unknown. In the English version, Lori has an older brother that is conspicuously absent.

Rad, Carlos, Alexis, and Kicker from Armada and Energon briefly appeared in the finale to strengthen Hasbro's connection of Armada, Energon, and Cybertron.

An Autobot that transforms into a traffic light. In the last episode of the series, he transforms (his transformation scheme being similar to that of Mudflap), and his name is revealed to be Signal Lancer in the Japanese version. His unusual alternate mode has made him a favorite among fans of the series.

The denizens of Speed Planet. Most appear in the form of cars (most resembling the "Blurr" model), or in robot modes that resemble the usual generic models used in the series. There are, however, some notable exceptions.

Buzzsaw - He transforms into a yellow and purple helicopter and could be seen flying overhead during several races on Velocitron. He resembles Cyclonus.

A blue, camera-like 'bot that served as announcer and "eye-in-the-sky" commentator for the big race.

The denizens of Jungle Planet. They all appear in animal form, and have transformations ranging from modern, mythlogical & prehistoric creatures, which means they must have visited Earth at some point. They include several that resemble an Apatosaurus, an owl, a deer, a giraffe, and a tropical bird.

Descendants of the original Transformers who came to the planet on the starship Atlantis. They inspired legends of monsters & supernatural creatures among the people of Earth. They were all captured and sealed in stasis pods by Crosswise for a number of years, until they were freed by Starscream. They have the ability to project an image around themselves that resemble cryptids (examples being Count Dracula, a werewolf, Bigfoot, and some dragons). They can also transform into large "Seeker ships" by merging with one another. They were all defeated and re-sealed, with the exception of Thunderblast and Lugnutz. However, Evac and Crosswise made a deal with Lugnutz, and released them to help in the final battle against Galvatron. Ultimately, a large number of them joined the space bridge project at the end of the series.

In the past, Planet X was populated by "mass production" types similar to Sideways and Soundwave, as well as numerous Mini-Cons fashioned in the same model as Laserbeak. There is a Japanese exclusive toy called Soundblaster, and his minion is a Laserbeak-type named Hell Buzzsaw.

Available exclusively to members of the Official Transformers Collectors Club, the short bi-monthly comic strip published in the club's newsletter - in addition to explaining away the plot holes that exist between the Armada, Energon and Cybertron animated series - expands the story of Cybertron to include many other characters. Primarily, these characters are from the parallel-universe-spanning Transformers: Universe toyline, but the comic has also featured several of the Cybertron characters not featured in the animated series. These include:

Dark Scorponok - An inhabitant of the Energon comic book universe by Dreamwave Productions, where he was killed by Megatron, but revived as a zombie-like creature hungering for sparks. The reality-warping effects of the black hole transported him from his home universe into the animated Cybertron continuity, where he found himself on Cybertron and attacked Skyfall. He transforms into a construction vehicle themed to look like a scorpion and an aircraft, and his jungle-planet themed Cyber Key activates twin blasters in his tail.

Skyfall - A Velocitronian native with no memories of his past who feels he has always been part of something greater than he knows, Skyfall came to Cybertron in hopes of finding out what that something was. He transforms into an A-10 Warthog, can manifest energon weapons and projects a protective forcefield. His toy was available exclusively through the Official Transformers Collectors Club.

Downshift - Having previously appeared during the Transformers: Energon animated series, Downshift was shown being badly damaged in battle and being rebuilt into a new form. He now transforms into a green and black muscle car, and his Cyber Key activates a grabber claw in his front grill. (The real-world origin of his sports car mode is highly debated by fans. It appears to be an amalgamation of various features found on Plymouth, Dodge, Chevrolet, and Ford sports cars from 1969 and 1970.)

Landquake - A Decepticon with powers like Skyfall, it seems this Transformer may be connected to him in mysterious ways. He transforms into a tank, and was also only available through the Collector's Club.

Unicron - The Cybertron toyline included a new incarnation of Unicron in the form of a futuristic alien tank, the existence of which was intended to prove that despite the destruction of his body and the creation of the black hole, Unicron - and evil - would always exist in some form. The club's exclusive comic proceeded to explain the origin of this body by revealing that, before joining the events of the Cybertron animated series, Soundwave was able to free Unicron's essence from its imprisonment within the black hole, allowing it to possess a small planet. Unicron's essence corrupted the planet quickly, and its inhabitants went to war; the planet was eventually destroyed, and Unicron emerged in his new body from within the remains. He has a planet-X cyber key which opens a port in his chest to reveal a triple-barreled cannon.

There are a number of Transformers in the toyline that do not appear in the show, most of which are American-exclusives.

Armorhide - An Autobot. Transforms into a tractor truck. Possesses an Earth-Type Cyber Key which unlocks a missile rack in his chest. His extra bio on Transformers.com states that he's a new recruit who enjoys lightening the mood with comedy.

Blurr - An Autobot who transforms into a futuristic race car. He is a remold of the Armada toy of the same name, and his appearance is based on the G1 season three character. His package bio mentions him as a racing veteran (such was true of his Micron Legend counterpart) and there are alternate bios for him which add that he is a veteran of the Armada and Energon battles. The new redesign of Transformers.com has modified Blurr's bio to depict the Armada/Energon version. He does appear in the show, but only as a civilian. He has a speed-planet designated cyber key which causes the guns mounted on him to fold to his sides, giving him a jet like appearance.

Brushguard - A Decepticon who transforms into an offroad vehicle. His bio describes him as a botanist who seeks to use Earth plants to develop biological weapons against the Autobots. Said to be the cousin of Overhaul, whom he is remolded and repainted from. He possesses the same cyber key power as Overhaul (being able to fire a missile from his chest), but the cyber key bears the earth insignia.

Cannonball - US exclusive repaint of Deluxe Red Alert, done as a Decepticon pirate. He has the same cyber key and its powers as Red Alert.

Demolishor - A repaint of the toy from Armada. Supposedly, the same character from Armada and Energon. His cyber key activates his left shoulder missiles (the key itself has the Cybertron appearance, but is ringed in purple and the decepticon symbol is invisible).

Excellion - A repaint of Hot Shot in the spirit of G1 Hot Rod. He's an irreverent and somewhat violent soldier. He has the same cyber key and its power as Hot Shot.

Hardtop - A Decepticon who turns into a dune-buggy (but not the hardtop-class despite his name). Possesses an Earth-type Cyber Key which turns his gun into a sniper rifle. His function is identified as a sniper. He has an extra bio that says he enjoys reading comic books.
